Everything I have read about using barley straw to kill algae mentions
that the likely mechanism in play is that in water the straw reacts with
sunlight to produce H2O2 (hydrogen peroxide). I have had luck bypassing
the straw altogether and adding H2O2 directly to the aquarium.

Some might be afraid of destroying the biofilter by adding peroxide, but
there has been some research into this and it appears that at
concentrations of 16.5 mg/L biofilms were still able to develop on
various substrates (Water Science and Technology, Vol. 38, Num. 8 - 9,
pp 283 - 289).

To achieve a concentration of around 9.5 - 10 mg/L using 3% H2O2, use 1
mL per gallon.
